First-Year Spectroscopy for the SDSS-II Supernova Survey
Chen Zheng, Roger W. Romani, Masao Sako +77
This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band…
A Study of the Type Ia/IIn Supernova 2005gj from X-ray to the Infrared: Paper I
J. L. Prieto, P. M. Garnavich, M. M. Phillips +53
We present extensive ugrizYHJK photometry and optical spectroscopy of SN 2005gj obtained by the SDSS-II and CSP Supernova Projects, which give excellent coverage during the first 1…
The Peculiar SN 2005hk: Do Some Type Ia Supernovae Explode as Deflagrations?
M. M. Phillips, W. Li, J. A. Frieman +41
We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002…
Flattening Scientific CCD Imaging Data with a Dome Flat Field System
J. L. Marshall, D. L. DePoy
We describe the flattening of scientific CCD imaging data using a dome flat field system. The system uses light emitting diodes (LEDs) to illuminate a carefully constructed dome fl…
RETROCAM: A Versatile Optical Imager for Synoptic Studies
Christopher W. Morgan, Paul L. Byard, D. L. DePoy +5
We present RETROCAM, an auxiliary CCD camera that can be rapidly inserted into the optical beam of the MDM 2.4m telescope. The speed and ease of reconfiguring the telescope to use…
